Release Notes

Installation

This is very abbreviated, intended mainly as a reminder for those
who have worked with milters before.
If it's your first milter, you should look on the web for more thorough
documentation.
Also, these instructions are pretty specific to FreeBSD, and will
have to be adapted for other OSs.

Make sure your sendmail is compiled with the MILTER option.
(Starting with version 8.13 this is enabled by default.)
You can use this command to check:

sendmail -d0.1 -bt < /dev/null | grep MILTER

If you don't see MILTER in the compilation options, you will have
to re-build sendmail.
